Study Notes
Engine
Types of Engines
- Internal Combustion Engine (ICE): Most common type, uses fuel combustion to generate power
- Electric Engine: Uses electric motors, powered by batteries or generators
- Hybrid Engine: Combination of ICE and electric motor
Engine Components
- Cylinders: Chambers where fuel is ignited to produce power
- Pistons: Move up and down in cylinders, driven by explosive force
- Crankshaft: Converts piston motion into rotary motion
- Camshaft: Operates valves, allowing air and fuel into cylinders
- Valves: Control air and fuel flow into cylinders
Engine Cycles
-
4-Stroke Cycle:
- Intake: Air and fuel mixture enters cylinder
- Compression: Mixture is compressed
- Power: Mixture is ignited, piston moves down
- Exhaust: Exhaust gases exit cylinder
- 2-Stroke Cycle: Simplified version, used in some small engines
Engine Performance
- Horsepower (HP): Measure of engine power
- Torque: Rotational force, measured in lb-ft or Nm
- Displacement: Engine size, measured in liters (L) or cubic centimeters (cc)
Engine Efficiency
- Fuel Efficiency: Measured in miles per gallon (mpg) or kilometers per liter (km/L)
- Emissions: Engine emissions, regulated by environmental standards
